Never (EVER) ever go to a quick lube place, like Jiffy Screwed, etc.

They are vandals at best, and crooks at worst.

The manual is correct, and they probably KEPT the Redline, and put in shit oil, or didn't even change it at all...or changed it with shit oil, and stripped the plug with the air tool, broke what was left of the splash guard, etc.

Sorry, but they all seem to suck big hairy moosecock.

You were probably fucked.

sorry.
